Mendel and His Peas
Directions: On the line before each statement, write T if the statement is true or F if the statement is false.
1. Genetics is the study of how traits are passed from parents to offspring.
2. Gregor Mendel studied pea plants because they reproduce slowly and have
easily observable traits.
3. Pollination in pea plants can occur in three ways.
4. Mendel began his experiments with pea plants that stayed the same from
one generation to the next.
5. He then crossed those plants to create true-breeding plants.
6. In Mendel’s studies of the colors of purple pea flowers, none of

the first-generation crosses had white flowers.
7. In those same experiments, about three-fourths of the second-generation
crosses had white flowers.
8. From those results, Mendel concluded that white flowers on pea plants
are a dominant trait.
9. In other studies, a trait that showed up in the same proportion of
second-generation crosses as white flowers did was yellow pods.
10. One trait that Mendel did not study in pea plants was the shape of the
plants’ leaves.
